URL: https://github.com/llvm/llvm-project/commit/22a748a51f2a2644f4dbc5e93615c9f3106e50d5 DIFF: https://github.com/llvm/llvm-project/commit/22a748a51f2a2644f4dbc5e93615c9f3106e50d5.diff LOG: [Headers] Revise conditional for rdrand64_step Downstream doc tooling doesn't like an #if between the doc and the function prototype. This change also guarantees that the prototype stays the same for 32/64 bit users.
